fllaims. (Cl. 119-61) This invention relates to improvements in sanitary hog troughs.

An object of the invention is to provide animproved sanitary hog trough which-will bepivotally supported ina suitable frame to be disposed in right side up position when feed is to be placed therein, and which may be swung on its pivots to an upside downposition for dumping and cleaning the trough.

Another object of the inventionis to-"provide an improved dumping hog trough which will i be pivotally supported in-a frame attachableto the side of the hog pen when the-trough is to be-us'ed for feeding purposes, said trough-being adapted to be swung out-of its frame and-into an upside down position for cleaningwithout havingto-ent'er the hog pen at any time, thereby not disturbing a sow and her litter of pigs when in said pen.

A further object of the invention is to provide an improved sanitary hog trough which will be highly efficient in operation, and relatively inexpensive to manufacture and produce. L

Other objects will appear as the description proceeds.

In the accompanying drawings which form a part of this application.

Figure 1 is a perspective view of the improved sanitary hog trough shown in operative position in its frame for containing hog feed, and

Figure 2 is a perspective view of the improved sanitary hog trough shown in upside down position, having been dumped for cleaning.

Like characters of reference are used throughout the following specification and the accompanying drawings to designate corresponding parts.

In carrying out the invention, there is provided an improved form of sanitary hog trough comprising a substantially rectangular shaped container I having relatively parallel side walls la, a front wall lb, a rear wall 10, and a bottom wall Id supporting the forwardly extending horizontal bearing eyes or sleeves 2 and 3, formed by curving and shaping the forward ends of the metal straps 4 and 5, Which are secured to the bottom of said container by conventional means to reinforce the same.

The supporting frame for the feed-container I comprises the spaced complementary side panels 6 and 1 each having a bottom edge 1a, a forward end lb and a rear edge 10. A first angle strip 8 is secured to each of the side panels adjacent the bottom edge 1a thereof, which angle strips have legs 8a extending towards each other and forming a container supporting flanges. A second angle strip 9 is secured to each of the side parentfrom the drawings.

panels adjacent the'rear edge 'lc'thereof; which second angle strips may have one end rigidly secured to or formed integrally with the adjacent end of the first angle strip, as is clearly-ap- The second angle strips are suitably secured to the wall I!) of a pig pen or the like, as by fasteners lfla whereby the side panels extend forwardly thereof.

Crossed bracing strips H and I2 are connected with the inner vertical edges of the second angle strips of said side panels 6 and T in any desired manner.

The headed pivot pins or bolts l 3 and I4 extend inwardly through the forward ends of the side :panels G and 1 and the attached'first angle strips BZ-said pins extending inwardly through the hearing eyes or sleeves 2 and 3, which form hinges or pivots for said container I so that the same may be positioned within the frame when food is to be placed therein. When it is desired to clean the container, it is only necessary to pivot the same moving it into the upside down position shown in Figure 2.

As is best shown in Figure 1, the side walls la of the container are guidably disposed between the side panels 6 and 1 when the container is in its upright position, whereby the side panels serve to retain the container in position therebetween. Suitable nuts or fasteners l5 are threadedly attached to the registering ends of the pins I3 and I4 and serve to prevent lateral spreading of the side panels 6 and 1 relative to each other, as well as serving to retain the container 1 in position relative to the panels. It is also contemplated that the forward ends 1b of the side panels and the coterminous ends of the first angle strips 8 serve to limit downward swinging movement of the container into its inverted position. For this purpose, it is intended that the axis of the sleeves 2 and 3 be spaced forwardly of the front wall lb a distance substantially equal to the distance the axis of the pins l3 and M are spaced rearwardly of the forward ends lb of the side panels, so that the forward ends of the side panels abut the front wall of the container and support the latter in an inverted position, as is clearly shown in Figure 2.

From the foregoing description, it will be apparent that there has been devised and provided a highly eflicient form of sanitary hog trough, which will be relatively inexpensive to manufacture and produce.

While the preferred embodiment of the instant invention has been illustrated and described, it will be understood that it is not intended to limit the scope of the invention thereto, as many minor 3 changes in detail of construction may be resorted to without departure from the spirit of the invention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is:

1. A sanitary hog trough comprising a pair of vertically extending laterally spaced sidepanels having a bottom edge and forward and rear ends, horizontally extending flanges on the bottom edges of said panels extending towards each other, means for attaching the rear ends of said panels to a supporting surface, a container having a bottom wall, relatively parallel side walls and a front wall, a pair of sleeves attached to said container and lying parallel to and forwardly of said front wall of said container, registering pivot pins attached to said side panels and extending into said sleeves, said pins pivotally mounting said container on said side panels, said walls engaging and being guided by said side panels when said container is in its upright position, the axis of said pivot pins being spaced rearwardly from the forward ends of said panels a distance equal to the distance the axis of said sleeves lies forwardly of said front wall of said container said forward ends of said side panels engaging saidfront wall of said container and supporting said container in a horizontal inverted position.

2. The combination of claim I including means carried by the inner ends of said pivot pins limiting lateral displacement of said container relative to said side panels.

3. A trough comprising a pair of vertically disposed laterally spaced side panels each having a forward, rear and bottom edge, flanges on the bottom edges of said panels extending towards each other, a container including a bottom wall.

having a forward edge and relatively parallel side walls extending upwardly of said bottom wall transversely of said forward edge thereof, said trough when in its upright position resting upon said flanges, a pair of sleeves attached to said trough with the axis of said sleeves extending parallel to and spaced forwardly of the forward edge of said bottom wall, pins extending through said panels adjacent the forward edges thereof, said pins extending towards each other and through said sleeves and pivotally mounting said 1 container on said panels, said side walls of said container engaging and being guided by said panels as said container is pivoted on said pins.

4. The combination of claim 3 including reinforcing straps secured to said bottom wall, said sleeves being secured to said straps.
